Abu Hurayra heard the Prophet, may Allah bless him and grant him peace, say, "Bad omens. The best of that is the good omen. They asked, "What is the good omen?" "A good word which one of you hears," he replied.  

سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ لاَ طِيَرَةَ وَخَيْرُهَا الْفَأْلُ قَالُوا وَمَا الْفَأْلُ؟ قَالَ كَلِمَةٌ صَالِحَةٌ يَسْمَعُهَا أَحَدُكُمْ
